Leonard X. Bosack (born 1952) is a co-founder of Cisco Systems, an American-based multinational corporation that designs and sells consumer electronics, networking and communications technology, and services.
[2] As of 2010[update], Bosack was the CEO of XKL LLC, a privately funded engineering company which explores and develops optical networks for data communications.
[5] It is widely reported that Lerner and Bosack designed the first router so that they could connect the incompatible computer systems of the Stanford offices they were working in so that they could send letters to each other.
The company produced revolutionary technology such as the first multiport router-specific line cards and sophisticated routing protocols, giving them domination over the market-place.
[4][5] Along with co-founding Cisco Systems, Bosack is largely responsible for first pioneering the widespread commercialization of local area network (LAN).
Bosack was inspired by his belief that by leveraging the inherent, but often untapped, physics of fiber optic components, data transmission speeds can be increased with devices that use less power, less space and require less cooling.
The foundation is recognized for financing a wide range of animal welfare and science projects, such as The Center for Conservation Biology at the University of Washington.
[4] In December 2001, a Mercury News article cited that a Stanford web site credits only Bosack and Lerner with developing the device that allowed computer networks to communicate intelligently with one another, despite Cisco spokeswoman Jeanette Gibson's claim that it was a group effort.
